FIX: A custom application stops responding when it uses the Submit adapter to submit more than 100 messages on a server that is running BizTalk Server 2006 R2 or in BizTalk Server 2009

On a computer that is running Microsoft BizTalk Server 2006 R2 or in BizTalk Server 2009, you register the Submit adapter that is included in the out-of-box SubmitDirect sample. You run the SubmitMessages.exe console application to submit a batch of messages. If the number of messages in the batch is more than 100, the console application stops responding.

This issue may occur when the Submit adapter is used. This issue may occur in custom applications and in the BizTalk Isolated Host.

This problem occurs because the BizTalk Server Message Agent creates a thread incorrectly.
